Buy Yokogawa EJA430A-DAH4B-77ED/FF1/X1/D1/N4 Pressure Transmitter – Alloy C-276, ATEX/FM Certified, Calibration Included, China Manufacturer

Product Overview

The Yokogawa EJA430A-DAH4B-77ED/FF1/X1/D1/N4 is a high-performance pressure transmitter engineered for demanding process environments where corrosion resistance and signal integrity are non-negotiable. This model operates on a 4 to 20 mA DC loop with BRAIN digital communication, enabling seamless integration into existing distributed control systems (DCS) while providing real-time diagnostic feedback. With a full Hastelloy C-276 wetted material construction, it is specifically tailored for aggressive media applications, including chlorinated hydrocarbons, sulfuric acid, and seawater injection systems. The calibrated measurement range spans 10 to 200 kPa (0.1 to 2 kgf/cm², 1.45 to 29 psi, 0.1 to 2 bar), making it ideal for low-to-moderate pressure monitoring in chemical, petrochemical, and upstream oil & gas operations.

Key Features & High-End Benefits

**Full Hastelloy C-276 Wetted Parts**
The use of Hastelloy C-276 across all wetted components eliminates the risk of pitting, stress-corrosion cracking, and oxidation in hostile chemical streams. This ensures long-term operational integrity and reduces unscheduled maintenance cycles in applications involving ferric chloride, wet chlorine, or high-temperature acids.

**BRAIN Digital Communication Protocol**
The integrated BRAIN protocol allows for remote configuration, multi-variable data retrieval, and predictive maintenance alerts without disrupting the analog 4-20 mA loop. This facilitates process optimization by enabling real-time adjustments to span, zero, and damping factors from the control room, minimizing field operator exposure to hazardous zones.

**High-Accuracy Silicon Resonant Sensor Technology**
The EJA430A leverages Yokogawa’s proprietary silicon resonant sensor, delivering ±0.075% accuracy and exceptional long-term stability. This reduces total cost of ownership by extending calibration intervals
